Looks like we got new hitchhiking pet rocks in a wheel onboard Percy :)

Bah moquette Marriott xD après j'aurais été très content si ça avait été le motif de celui d'Atlanta la ou se tient la Dragon Con

Very happy to head back to Houston to attend #LPSC2025 😁
I will have both an oral presentation and a poster, focused on Stratigraphy, Geomorphology and also Geochemistry (yes, even me can do that sometimes 😅)

I'm back at @cnes.bsky.social and I mean business for ChemCam on Curiosity 😎

Et l'inverse est vrai aussi, les tubes à échantillons font de bons sabres laser 😜

Just looked at the latest Percy's Navcam from Sol 1354, and here we are, atop the crater's rim, getting our first look at what lies beyond Jezero! 🤩 Hills seen in a distance through the haze are ~10 km away from the rover's position

Browsing accros the "Mars" algorithm of BSky, I recommend you doing it!
But I'm really upset, how could a complotist account with endless bullshit like that have much more followers than people actually studying Mars for a living? (More than me clearly 😅) Don't let BSky become the worse of X...

On this day 7 years ago, I defended my PhD in Geology 👨🎓 at Univ. Bourgogne
7 years of post-doc in, I'm no longer an early career, but that's no problem, as I'll start my "main" career in September as an Assitant Professor in GET Toulouse at Univ. Paul Sabatier ! 🥳

We all know that sampling tubes are little lightsabers in the waiting. Mine is just keeping some advance 😉 happy #MayThe4th!

Based on these data, we highlight 4 hydrogeological cycles, indicating that the lake-level in Jezero fluctuate during and in-between episodes of deltaic construction, with variations up to 10 meters at the time of Kodiak being deposited

In turn, these facies also allow us to highlight 3 different units, associated with 3 individual mouth bars : unique discrete piece of deltaic construction

Main Highlights ⚡
👉We use data from @NASAPersevere
👉We propose a fine-scale, high-resolution analysis sedimentary analysis of Kodiak
👉We provide a data-driven sequence stratigraphy analysis for the very first time on another world than Earth! 💪
